Purpose:
To develop a new type of vascular access (VA) avoiding permanent arteriovenous (AV) shunting and intravenous catheter placement using a silicone plug inserted in the vessel wall.
Method:
Four different animal studies were conducted to verify the biologic safety of the concept, to check resistance to infection and accessibility and midterm patency.
Results:
The circulating ports were found to be very easy to puncture, extremely resistant to infection and their midterm patency rate was acceptable.
Conclusions:
The circulating port seems to be a very promising hemodialysis (HD) access method, but it still has to be tested in clinical situations.
